5.1. Service Provider Data Center
The Data Center simulates two customers, PC-LAN (Private-Private) and C-LAN (Private-
Public-Private). These customers each have their own image of Avaya Communication Manager.
These Avaya Communication Manager images both run on the same blade (HT1) in the Avaya
SBS3000 environment. The Data Center is privately addressed.
The PC-LAN based Avaya Communication Manager image has VPN based enterprise sites (A1
and A2).
The C-LAN based Avaya Communication Manager image has NAT based enterprise sites (B1
and B2).
One LSP is configured for each customer site. To configure additional LSP enterprise sites refer
to Section 6.1 for PC-LAN configuration and Section 6.2 for G650/C-LAN configuration.
The Data Center contains a network based Juniper VF 3000 SBC Session Border Controller. The
Juniper VF 3000 SBC provides H.323 and H.248 NAT processing to the WAN. The Juniper VF
3000 SBC also provides firewall functionality.
The Data Center also contains a Juniper NetScreen-25 Firewall VLAN supported device. The
NetScreen-25 Firewall provides NAT processing and firewall functionality to the WAN for the
LSP Solution.
5.2. MPLS Core
An MPLS core WAN network is used between the Data Center and the Enterprise sites. The
MPLS core network is composed of Cisco routers. MPLS IP VPNs are configured between the
Data Center and enterprise sites.
5.3. Customer Enterprise Sites
The Distributed Service Model enterprise sites access the Data Center via a public WAN. The
remote sites use local private IP addressing. The enterprise sites may use either private-to-private
VPN tunnels, or private-to-public NAT addressing, to access the Data Center via the public
WAN.
All of the enterprise sites contain a Checkpoint firewall for security. The Checkpoint also
provides IP NAT functionality for those sites that use private-to-public NAT addressing to
access the Data Center.
Enterprise sites contain Avaya Media Gateways with Local Survivable Processors (LSPs). Local
Survivable Processors (LSPs) provide local IP telephony in case connectivity to Avaya
